PHYSICAL DATA

The standard design for the Larkin low profile evaporators incorporates an efficient hot gas loop in the drain pan� Utilizing a hot gas loop is ideal for hot gas defrost applications where high temperature gas can be maintained to defrost both the evaporator drain pan and coil� For these models, an insulated drain pan is standard�

For applications where cooler (lower) temperature hot gas is used for defrosting, Larkin offers optional electric heater elements in the drain pan to ensure quick and efficient defrost of the drain pan allowing condensate to drain quickly, saving the hot gas for efficient evaporator coil defrost�

If the optional electric heating element drain pan is preferred, please specify when ordering, there is no additional charge�

* Hot Gas Loop Piping Connections

n For reverse cycle defrost piping:

• 5/8 ID Inlet

• 5/8 OD Outlet

n For 3-pipe defrost piping:

• 5/8 OD Inlet

HOT GAS REVERSE CYCLE KITS

The hot gas unit coolers can be used in reverse cycle hot gas defrost systems using multiple evaporators connected to one condensing unit� Generally, not more than one-third of the system defrosts at one time�

During the reverse cycle defrost, the reversing valve, located in the compressor discharge line, diverts hot gas through the suction line to the evaporator� See piping view in Figure 1� The suction line check valve directs the hot gas through the drain pan loop which prevents condensate in the pan from freezing� The hot gas exits the loop at the pan loop outlet header and enters the evaporator through the check valve assembly� As the hot gas defrosts the coil, heat is removed from the hot gas and eventually it condenses into a liquid and exits the coil at the distributor sideport� The liquid then flows through the check valve of the thermostatic expansion valve bypass assembly, around the thermostatic expansion valve, and into the system liquid line� The liquid refrigerant then feeds other evaporators on the cooling cycle, evaporates, and returns to the compressor through their suction lines�

Recommendation is that both check valve kits are ordered (For hot gas models with the hot gas loop drain pan ONLY):

NOTE: The drain pan check valve kit can be ordered as an independent item� But the suction line check valve kit must be ordered with the drain pan check valve kit in order to complete the piping�

NOTE: When using the hot gas units with a hot gas loop drain pan on 0°F applications and below, an insulated drain pan is required.

HOT GAS REVERSE CYCLE KITS (cont.)

In the refrigeration cycle, the thermostatic expansion valve bypass assembly check valve only allows refrigerant flow through the thermostatic expansion valve and into the evaporator coil� As the refrigerant vapor exits the coil at the suction line, the check valve of the drain pan loop check valve assembly prevents the refrigerant vapor flow through the drain pan loop�

Factory-engineered assemblies (kits) are available for both shipped-loose and factory-installed at an additional cost to complete the reverse cycle piping and components� The suction line check valve assembly includes the suction line check valve and the piping for both the suction line and the connection to the drain pan loop inlet header� In order for the suction line check valve assembly to be mounted, the drain pan loop check valve assembly must be used� The drain pan loop check valve assembly includes the check valve, suction line tee and a bent pipe� The thermostatic expansion valve bypass assembly option includes the check valve, tee and necessary piping� In order for the thermostatic expansion valve bypass assembly option to be complete, a thermostatic expansion valve must be selected by the sales engineer� The thermostatic expansion valve bypass assembly option is dependent on the body style of the thermostatic expansion valves which includes the Sporlan® SQE, SBF, EG and the Flow Controls HFESC body styles� The factory-installed thermostatic expansion valve bypass assembly option must have the thermostatic expansion valve selection included on the order for the hot gas unit cooler�

To increase the efficiency, higher performance and greater system protection, a heat exchanger may be beneficial to the system� In order to use a heat exchanger, the thermostatic expansion valve bypass assembly option must be modified� See the piping view in Figure 2� The modification includes rerouting the pipe from the thermostatic expansion valve bypass check valve to the inlet connection of the liquid line to the heat exchanger� A pipe needs to be routed from the liquid line outlet connection of the heat exchanger to the inlet connection of the thermostatic expansion valve�

The electrical control option includes an adjustable defrost termination and fan delay control (DTFD) which is standard� For an additional cost, an optional (2) control electrical system is available with one adjustable control for defrost termination (DT) and one fixed control for the fan delay (FD)� For both the DTFD and DT adjustable controls, the remote bulb position is with the bulb strapped to the piping of the thermostatic expansion valve bypass assembly option between the distributor sideport and the check valve� When the thermostatic expansion valve bypass assembly is shipped-loose, the installer will need to position the remote bulb� When the thermostatic expansion valve bypass assembly is factory-installed, the remote bulb should already be properly installed�

3-PIPE HOT GAS DEFROST

The hot gas defrost unit coolers conform to the standard 3-pipe hot gas system using a check valve assembly, an electrical control to terminate the defrost, and a hot gas solenoid valve� The check valve assembly transports the hot gas between the drain pan loop and the sideport distributor of the coil� The check valve assembly kit is available for shipped-loose or factory-installed for an additional cost�

The electrical control option includes an adjustable defrost termination and fan delay control (DTFD) which is standard� An optional (2) control electrical system is available with one adjustable control for defrost termination (DT) and one fixed control for the fan delay (FD) for an additional cost� For both the DTFD and DT adjustable controls, the remote bulb position is with the bulb strapped to the suction line to insure a complete defrost� The remote bulb is positioned by the installer� The hot gas solenoid valve must be ordered separately and will be shipped-loose� The thermostatic expansion valve could be ordered separately and shipped-loose or the thermostatic expansion valve could be factory-installed with a liquid line for an additional cost�

The liquid line is designed for the body styles of the Sporlan SQE, SBF, EG and the Flow Controls HFESC thermostatic expansion valves� The thermostatic expansion valve needs to be selected by the sales engineer� In a typical 3-pipe, multiple evaporator system, the compressor discharge defrosts the evaporator� The liquid/vapor mixture of refrigerant after defrost, however, returns to the common suction line of the system� In order to provide sufficient re-evaporation of the liquid vapor mixture and sufficient heat for defrost, no more than one-third of the system should be defrosted at one time� Some means of control in the 3-pipe hot gas system should be supplied to regulate the large amount of liquid returning to the compressor, refrigerant slugging can otherwise damage the compressor�
